Bolbhav Plus WebApp
About Bolbhav Plus
Bolbhav Plus is a web application designed to allow users, especially traders and village level aggregators to view the distribution of prices across select APMC mandis. The ability to view and compare price distributions across different mandis is the USP of this product. This documentation is a comprehensive guide to the features, architecture, and functioning of the application.
Key Features
Bolbhav Plus follows a linear application flow. Users choose their crop, crop+variety, and optionally mandi, and can view the price distributions corresponding to their selections. The two main pages are the home screen and the mandi view screen. Both of these pages exist in either the “default” state (default crop-variety) or the “filtered” state (user-selected crop-variety).
Here are some of the key features of Bolbhav Plus:
User can see the distribution of prices in a tabular format. This can be at the crop level, crop-variety level, and crop-variety-mandi level
User can subscribe for WhatsApp notifications when the first 10 receipts of a selected crop (or crop-variety) are approve.
View historical price data.
